Standardized assessment of basic addition combinations where both addends are 0 through 10, and the sum is 20 or less. Includes 121 unique facts from 0+0 to 10+10.
The ability to recall basic addition facts quickly and accurately without counting or calculating, typically within 2-3 seconds per fact.
Standardized assessment typically featuring 20-100 problems completed in 2-5 minutes, depending on grade level and objectives.
Groups of related facts using the same numbers. Example: 7+5=12, 5+7=12, 12-7=5, 12-5=7.

A + B = B + A, reducing the number of facts to memorize from 121 to approximately 66 unique combinations.
(A + B) + C = A + (B + C), useful for adding three or more numbers.
A + 0 = A, any number plus zero equals the same number.
- Start with zeros and ones: Easiest facts to master
- Learn doubles: 1+1, 2+2, 3+3, etc.
- Master near-doubles: 6+7, 8+9 (one more than doubles)
- Use making ten: 8+5 = 8+2+3 = 10+3 = 13
- Count on: Start with larger number and count up
• Confusing addition with subtraction
• Forgetting to memorize facts thoroughly
• Relying too heavily on counting instead of recall
• Not practicing both orders of addends
• Mixing up similar-looking facts

Section 1: 3, 6, 7, 3, 9, 9, 4, 7, 10, 6
Section 2: 4, 9, 5, 8, 7, 10, 3, 4, 11, 2
• Identity Property: A + 0 = A
• Successor Property: A + 1 = next number

Use doubling strategy for efficiency
Section 1: 4, 6, 8, 10, 12, 14, 16, 18, 20, 2
Section 2: 5, 7, 9, 11, 13, 15, 17, 19, 3, 19
• Doubling Strategy: A + A = 2A
• Near-Doubles: Use doubles + 1
• Pattern Recognition: A + (A+1) = 2A + 1
A + B = C (where A,B ≤ 10, C ≤ 20)
Accuracy × Speed = Fluency
(0+0 through 10+10)
